“…Gulati et al, 2012), studies addressing coordination across these system levels are scarce (Vargas et al, 2016). Therefore, although a substantial body of research has addressed care coordination across professional and organizational domains, often locally or related to a specific condition (e.g., Gadolin et al, 2022; Gorin et al, 2017; Karam et al, 2018; Røsstad et al, 2013; Schultz et al, 2013; Ugyel, 2019; Vázquez et al, 2017), research addressing determinants of actors' coordination across healthcare system levels remains essential (Hughes et al, 2020; Raus et al, 2020; Suter et al, 2017; Vargas et al, 2016). Whereas coordination across system levels is always pivotal in order to ensure efficient healthcare provision, the COVID‐19 pandemic has made the effects of fragmentized healthcare systems even more palpable in terms of illustrating the hindrance it constitutes for coordination across healthcare system levels (e.g., Armocida et al, 2020; Khalid & Ali, 2020).…”
